When a transient exceeds the 8.65 V minimum breakdown, the Zener junction avalanches and clamps the voltage to 13.4 V maximum at 112 A. The 1500 W peak pulse rating is the energy it absorbs before failure; for a 10/1000 µs surge, that is the safe limit per event. The DO-201 axial body handles the thermal pulse of a 1500 W surge without derating at 25°C; at elevated ambient, derate per the datasheet curve. Power line protection is marked 'No' — this device is intended for DC signal or low-voltage rail clamping, not AC mains transient suppression. Use it on 5 V, 6 V, or 7.78 V DC buses where a unidirectional clamp is acceptable. ## Obsolete — sourcing through independent channels Diodes Incorporated lists the 1.5KE9V1A-T as Obsolete.","metaTitle":"1.5KE9V1A-T Diodes Inc TVS Zener, 1500W, DO-201","metaDescription":"Diodes Inc 1.5KE9V1A-T Zener TVS, 1500W peak pulse, 7.78V standoff, 13.4V clamp, DO-201 axial.
